Abstract
Traditional fermented beverages have been consumed worldwide for centuries. Such is the case of "Chicha de siete semillas" which is originally from the province of Huanta, in Ayacucho, Peru. In this work we have analyzed the chemical composition and bacterial diversity of products manufactured from six producers, who have used different combinations of cereals, pseudocereals, legumes and aromatic herbs, although maize was present in all of them. The fermented beverages had a low pH, mainly due to the production of lactic acid, whereas ethanol was, in general, present in low concentrations. Most of the products were rich in GABA, the content of biogenic amines being very low, as corresponds to a product with a short maturation time (less than 4 days). A metataxonomic analysis revealed that Streptococcaceae and Leuconostocaceae families were dominant in the majority of the beverages, Streptococcus spp. and Leuconostoc spp. being the representative genera, respectively. The result was corroborated by culture-dependent techniques, since these were the most abundant genera isolated and identified in all samples, with Streptococcus macedonicus and Leuconostoc lactis as representative species. In lower proportions other isolates were identified as Lactobacillus delbrueckii, Lactiplantibacillus plantarum, Furfurilactobacillus rossiae, Weissella confusa and Enterococcus faecium. The genetic profile of 26 S. macedonicus isolates was determined by RAPD-PCR and REP-PCR, showing five different patterns distinguishable with the first technique. One representative strain from each genetic pattern was further characterized and used to ferment a maize-based matrix (with saccharose) in order to know their technological potential. All strains were able to ferment the beverage at 30 °C in a short time (about 6 h) reaching a pH below 4.5 and they remained viable after 24 h; the main organic acid contributing to the pH decrease was lactic acid. Therefore, S. macedonicus is a good candidate for being part of a putative starter culture, since it is a species well adapted to this cereal-based food niche.

Transcriptome profiling of human col\onic cells exposed to the gut pathobiont Streptococcus gallolyticus subsp. gallolyticus. PLoS One 2023; 18:e0294868.

Abstract
Streptococcus gallolyticus sp. gallolyticus (SGG) is a gut pathobiont involved in the development of colorectal cancer (CRC). To decipher SGG contribution in tumor initiation and/or acceleration respectively, a global transcriptome was performed in human normal colonic cells (FHC) and in human tumoral colonic cells (HT29). To identify SGG-specific alterations, we chose the phylogenetically closest relative, Streptococcus gallolyticus subsp. macedonicus (SGM) as control bacterium. We show that SGM, a bacterium generally considered as safe, did not induce any transcriptional changes on the two human colonic cells. The transcriptional reprogramming induced by SGG in normal FHC and tumoral HT29 cells was significantly different, although most of the genes up- and down-regulated were associated with cancer disease. Top up-regulated genes related to cancer were: (i) IL-20, CLK1, SORBS2, ERG1, PIM1, SNORD3A for normal FHC cells and (ii) TSLP, BHLHA15, LAMP3, ZNF27B, KRT17, ATF3 for cancerous HT29 cells. The total number of altered genes were much higher in cancerous than in normal colonic cells (2,090 vs 128 genes being affected, respectively). Gene set enrichment analysis reveals that SGG-induced strong ER- (endoplasmic reticulum) stress and UPR- (unfolded protein response) activation in colonic epithelial cells. Our results suggest that SGG induces a pro-tumoral shift in human colonic cells particularly in transformed cells potentially accelerating tumor development in the colon.

Abstract
S. bovis/S. equinus complex (SBSEC) includes lactic acid-producing bacteria considered as the causative agent associated with acute rumen lactic acidosis in intensive ruminants. Considering the limited information on the detailed characteristics and diversity of SBSEC in Korea and the emergence of antimicrobial resistance (AMR), we investigated the diversity of SBSEC from domestic ruminants and verified the presence of antimicrobial resistance genes (ARGs) against several antimicrobials with their phenotypic resistance. Among 51 SBSEC isolates collected, two SBSEC members (S. equinus and S. lutetiensis) were identified; sodA-based phylogenetic analyses and comparisons of overall genome relatedness revealed potential plasticity and diversity. The AMR rates of these SBSEC against erythromycin, clindamycin, and tetracycline were relatively lower than those of other SBSEC isolates of a clinical origin. An investigation of the ARGs against those antimicrobials indicated that tetracycline resistance of SBSECs generally correlated with the presence of tet(M)-possessing Tn916-like transposon. However, no correlation between the presence of ARGs and phenotypic resistance to erythromycin and clindamycin was observed. Although a limited number of animals and their SBSEC isolates were examined, this study provides insights into the potential intraspecies biodiversity of ruminant-origin SBSEC and the current status on antimicrobial resistance of the bacteria in the Korean livestock industry.
